I need to build up the points on my Ferguson plow shares. Shins could use some help also. There is already some hard surface material there but getting worn. No idea what it is. I have a two welders, but both AC. What do you recommend for rod? I cannot pre-heat, if that is required. thanks!

check out 7014 or 7018 for AC. High nickel content rod - can't remember number- was in Lincoln book for build up wear points.
 
Some people are using hardfacing MIG wire in their MIG machines . Here is some arc rod. They used to have specs for Brinnel and Rockwell hardness for each type hardface rod . Some are more impact only and some are abrasion and impact. Many will get surface cracks but still adhere well to the base metal. Preheat in this case is room temp but not cold out .

We always used stoodite welding rods. They are a hard surfacing rid that does not get too brittle. My Grand Father used them 75 years ago in his black smith shop. They are still available. I use them on chisel plow points and field cultivator sweeps.
 
I have Lincoln's "Hardfacing Product Catalog" which is a few years old, but I doubt that the products change much. The catalog has a two page list of stick electrodes for hardfacing, arranged by intended usage: build-up, metal to metal wear, severe impact, metal to earth wear, etc. I would expect the same information to be available online at the Lincoln Electric website.

i'd grind off the hard facing and build it up with a good stainless rod. as it wears you can simply add more. my experience with hard facing is that multiple layers tend to come off. stainless under hard facing works great as a "cushion" for the hard facing. eutectic use to make some of the best welding rods I've ever used.
 
Stoodite, usually followed by a number, like Stoodite 21, is the item name for hardfacing, (and possibly other types of specialty rods), made by the Stoody company. Since the last time I had a reason to look for the Stoody company online, they have been bought by ESAB. I was able to get to the rod you suggested by googling Stoodite, but it would probably be more direct to google ESAB, or even Stoody.
